Is yawning contagious?

Absolutely! In fact, yawning is so contagious that even reading about yawning can make you yawn.(Go ahead and get it out of your system) Studies have shown again and again that people who see other people yawn – even in videos – are more likely to yawn. Yawning most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality. It is commonly associated with tiredness, stress, sleepiness, or even boredom and hunger. In humans, yawning is often triggered by others yawning (e.g. seeing a person yawning, talking to someone on the phone who is yawning) and is a typical example of positive feedback. This “contagious” yawning has also been observed in chimpanzees, dogs, cats, birds, and reptiles, and can occur across species.
